ABSTRACT:
The high temperature combustion of hydrogen and oxygen is used to transform halogenated refrigerant gases (HRGs) and halons to produce calcium fluoride salts. Calcium carbonate is also produced by a series of chemical processes. Calcium chloride is partially consumed by the process by reaction with fluoride released during the high temperature combustion of the HRGs. Calcium chloride is also produced in the process during scrubbing of chlorine and during the recovery of ammonia used to remove carbon dioxide. The calcium chloride produced during the process can be used in the combustion reaction to further produce calcium fluoride.
